There are two savannas at Kidani, Sunset, the very large savanna which has 80% of the savanna view rooms and has giraffes, and Pembe, the much smaller savanna which does not have giraffes. Thus, one possible request is Sunset savanna view. As to location, the Kidani building is very long (about 3/4 mile end to end). There are two wings, north and south, and tthe pool is of the north wing and the bus stop off the south. Getting close to one usually means not being that close to the other.
If close to pool is more important, I would request a room near the Rafiki elevator which is one of the three elavators on the north wing (down it to ground floor gives you shortest possible walk from building to a gate entrance to the pool area). However, that will leave you some, but not a real long, walk to the bus stop. If close to the bus stop is preferred, request either near the Timon elevator or near Community Hall, which will put you on south wing with a very short walk to an exit door that leads right to the bus stop. Views from those areas are fine and those requests need to be made through Members' Services.
I would avoid requesting close to lobby. If you were to get that, it would also be fine both for being fairly close to pool and bus stop and for views. However, there have now been a huge number of members who have stayed at Kidani and been stuck in rooms near the end of the wings. The lesson learned by those members is that they never again want to be in those rooms near the end of the wings because of the long walks to lobby, pool, restaurant, and bus stop. If you want an example of how long the walks are, think of it this way: the walk from an end room on the north wing to the bus stop is about the same distance as walking from the base of the World of Nations, after coming over from Future World, to Germany. Those members now usually request close to lobby. Moreover, close to lobby is one of the requests you can make when doing online check-in that applies mainly to cash guests. The result is that there have now been many reports of those who have requested close to lobby not getting that request met, and, instead, ending up back in those rooms near the end of the wings, because the resort's default position, when it cannot meet a location request, is not to look for something fairly close to what you requested, but instead stick you in any available room anywhere in the resort (which is usually those rooms far from the lobby).
